SPECIFICATION forming part of Letters Patent No. 782,420, dated February14, 1905,

Application filed June 16, 1904. Serial No. 212,802.

To all whom it may concern.-

Be it known that we, 'THOMAS GEORGE SEARLES, residing at 867 Old Kentroad, and MAURICE SHEARER, residing at 809 Old Kent road, London,England, subjects of the King of Great Britain and Ireland, haveinvented certain new and useful Improvements Pertaining to the Bindingof Loose or Folded Sheets of Paper or other Material, of which the. following is a specification. V

This invention relates to certain new and useful improvements pertainingto the binding of loose or folded sheets of paper or other material, andhas for its object to provide means whereby such sheets of paper orother material may be securely and firmly-held or locked in a binder orfile whenever a required or desired number of sheets,whether one orseveral, may have been collected and placed therein.

The accompanying drawings illustrate the invention.

Figure 1 shows a file or hinder open and fitted with our improvements.Fig. 2 is an end view of the spring-back of the binder, showing serratedpins or prongs and metal clamping, strip, together with springfastening-plates. Fig. 3 is a front elevational view of springfastening-plate, and Fig. 4 illustrates in front elevational VIEWSsuitably-perforated clamping-strips. Fig. 5 is a perspective view of aportion of binder.

In carrying the invention into effect the file or binder is constructedwith a spring or stiff back a, Figs. 1 and 2, of metal or other suitablematerial, attached to which are one or more pins or prongs Z) of anysuitable section. These pins or prongs I) are jointed at a to one sideof the spring or stiff back a, so as to form a hinge to enable said pinsor prongs Z) to be put into a suitable position to place the loose orfolded sheets thereon. After any required number of sheets have beenplaced on the pins or prongs '6 the sheets are held in position by theclamping-strip c of suitable metal or material with perforations tocorrespond with the pins or prongs b aforesaid, said strip 0 beingribbed or turned over at its top to hold firmly against the sheets,and'it can be removed and replaced when necessary. In Fig. 4 areillustrated two suitable arrangements of slots or perforations in thestrip 0 for the purpose.

As more particularly illustrated in Fig. 2, the pins or prongs 6 areserrated to receive the clamping-stripe, which thus firmly hold thesheets in position. The points of the pins or prongs b are made conicalwith shoulders,

2 at e, and the inner side, of said channel is perforatedcorrespondingly with the perforations of the spring-fasteners d. In thechannel e is inserted a strip of metal or other suitable material f,which closes the holes in the channel, thus preventing the points of thepins or prongs 6 being inserted until it is re.- quired to fasten thefile or binder. When it is desired to do this, the strip fis withdrawnfrom the channel 0 and the points of the pins or prongs b are thenenabled to be forced through the holes of the spring-fasteners. Theholes in the spring-fasteners 61 being smaller in diameter than theconical heads toward the points of the pins or prongs b, thesaid pins orprongs cannot be withdrawn when .they are forced through beyond theshoulders. Hence the fastening of the file or binder then becomespermanent.

The spring or stiff back a of the binder or file may be provided withfiat or other springpieces arranged 'or placed against or near thehinging-points of the pins orprongs or in other suitable position tostrengthen the same and increase the spring force, if necessary.

What we claim as our invention, and desire to secure by Letters Patent,is-

1. In binders or files for loose or folded.

sheets of paper or other material the springback a formed with channelededge e in combination with the serrated and conioallypointed pins orprongs b and spring fastening-plates cl substantially as shown anddescribed. v

2. In binders or files for loose or folded sheets of paper or othermaterial the springback a formed with channeled edge e in combinationwith the serrated and conicallypointed pins or prongs Z), the perforatedclamping-plate 0, spring fastening-plates d and removable strip fsubstantially as shown and described.

In testimony whereof we have signed our names to this specification inthe presence of 5 two witnesses.
